TENSION BRACKET FOR WI-IIP ROLLERS.

` Application filed February 2, 1928. Serial No. 251328.

This invent-ion.relates to loom fixtures and attachments, and particularly to an improved tension bracket 'tor whip rollers, the object being to provide a Construction which willahold thewhip roller in correct position at all times while allowing a limited yeld ing motion. 4

I Another object of the invention is to provide a tension bracket for whip rollers of looms, wherein the parts are so made that the ordinary bracket heretofore used may be removed and the improved bracket substituted without changing any of the parts.

A further object, more specifically, is to provide a bracket for whip rollers of looms, wherein a swinging support is provided for the roller and spring means arranged in the path of movement of the swinging support so as to limit and yieldingly resist such movement.

In the accompanying drawing- F igure 1 is a perspective View of part of a loom showing a bracket embodying the invention, together with certain associated parts.

Figure 2 is a top plan View, on an enlarged scale, of the bracket shown in Figure 1.

Figure 3 is a sectional view through Figure 2, approximately on line 3-3.

Figure 4: is an edge view of the structure shown in Figure 3.

F igure 5 is a fragmentary sectional view through Figure 3 on line 5-5.

F igure 6 is a detail fragmentary sectional view through Figure 4 on line 6-6.

Referring to the accompanying drawing by numericals, 1 indicates a loom of a desired kind, provided with any desired kind of beam 2 and suitable supports therefor. Associated with the beam 2 is a roller 3 commonly known as a whip roller. The yarn passes over the whip roller 3 in the usual manner and extends to the front of the loom. Heretofore, brackets of different kinds have been provided 'or supporting the whip roller 3, but these brackets merely supported the roller in a manner to permit the same to rotate but not yield 'when strain is brought to bear thereon, as for instance, at the time of heating up of the weft. In order to provide a proper support for the roller 3, and at the same time permit a movement of the roller when extra strain is brought to bear thereon, the bracket shown particularly in Figures 2 to 6 has been de- 'support 12.

signed and so formed as to take the place of the ordinary ,bracket on the loom 1 as indicated in Figurel. When in position, an extra strain on the roller 3 will cause the same to move againstthe action of the spring 4. It will bennderstood that there is'abracket at each end of roller 3, 'and that the description of one will applyto both, as both brackets are identical and function in the same way. y

The loom l isprovided with an extension 5, which is in turn formed with spaced beads 6 and 7 (Figure 5) and between these beads the bracket standard` 8 is fitted. A bolt 9 extends through the extension 5 andthrough the slot 10 in the standard 8 whereby this standard maybe clamped rigidly in place and at different heights. The slot 10 is important in that it is sometimes necessary to raise or lower the roller 3 according to the certain kind of goods being woven. By providing slot 10,-the bracket may be raised or lowered to substantially any desired extent. Integral with the standard 8 is a web 11 which merges into the tubular spring This spring support has a closed end 13 and an open end 14. Spring 4 is loosely positioned in this support and bears against end 13 and also against the end 15 of the swingng roller support 16. A stud 17 acts to center spring 4:. The sup port 16 is formed near its lower end with a thickened U-shaped structure 18 having an opening 19 which will permit the end of the roller to be inserted or removed at any time. The extrene lower' end of the support 16 is provided with a tubular enlargement 20 which accommodates the bolt 21. This bolt extends through a suitable aperture in standard 8, through tubular extension 20, washer 22, lock Washer 23 and nut 2 1. It will be noted that the movement of the roller 3 is on the arc of a circle, the center of which is the center of bolt 21. As the distance between the bottom of member 18 and the center of bolt 21 is comparatively short, the movement of the roller 3 will be small but sufcient to relieve the extra tension brought on the yarn. The spring' 4 and the spring support 12 will limit the swinging movement of support 16 in one direction, while an extension 25 on standard 8 will limit the swinging movement in the opposite, direction. This will prevent any accidental unusual swinging movement of roller 3. Notwithstanding the swinging movement of roller support 16, the roller 3 may be in'- serted or removed at any time in the usuai manner.

What I claim is:

1. A tension bracket for whip rollers of looms, comprising a supporting bracket standard, a swinging support pivotally mounted on said bracket standard, means presnting a sooket crri'd by the braket standard, a spring positioned with one end in said 'socket and the other end 'against said support for yildingly holding the support in a given position and means for bodily a'djusting said bracket standard vertically, said spring, 'said roller and said swinging support being moved with the braeket standard.

2. A tension bracket for whip rollers, co'm'pri'sifg a b'racke't 'standard 'and means integral therevvith forming a socket, a swinging `'support pivotally mounted on 'said standard and formd With a hearing socke t for reoeiving the journal pin of the whip roller; a 'spring po'sitioned in said socket and aeting on 'said 'support for 'resilfently holding the same in a given position and means for bodily adjustng said bracket standard and all parts carried th'ereby.

3. A tension bracket for Whip roller-s, comprising a bracket standard formed with a slot and With an apertire, a ,Web formed integral with the standard and extending upwardly and laterally therefrom and a sofcket member carried at the upper end of said Web, a pivot member eXtending through said aperture a holder formed With anaperture for ahcommodating said pivot member whereby the holder is pivo'taliy m'ounted on said 'standard said hold'er having a hearing soe-ket for rec'ei'vin'g one 'end of a Whip roller and 'a head at the oppo'sit'e end, a spring partially positioned in said 'first mentioned so'cket and 'atting `on said head for resiliently holding the holder in a. given position and a lamping member 'extending through said 'slot for adjustably supporting the bra'ck-et standard.
